Bauxite | The Aluminum Association

Bauxite is a rock formed from a reddish clay material called laterite soil and is most commonly found in tropical or subtropical regions. Bauxite is primarily comprised of aluminum oxide compounds (alumina), silica, iron oxides and titanium dioxide. Approximately 70 percent of the world's bauxite production is refined through the Bayer chemical process into alumina. Alumina is then refined ......

Guinea Coup: Impact on Aluminum and Bauxite

19/09/2021 · Raw Material Availability. No significant impact in the short term (2–3 months). Proactive Alert (Bauxite) Alert Coup in Guinea raises concerns on Bauxite supply. Bauxite prices spiked to an 18month high, as buyers in China and overseas are concerned about the stability of bauxite supplies postcoup. After Australia, Guinea is the secondlargest bauxite producer globally, accounting for 25 ......

Refractory Grade Bauxite

03/08/2018 · The bauxite used for producing abrasive, chemical, and refractory products must fulfill much more rigid compositional requirements than the crude ore that is commonly used for aluminum metal production, as shown in Table II.
